scanf() Format Specifiers

scanf() format specifiers tell the compiler what to expect from the user as a data type. The example above uses the %s specifier, which is used to scan an entire string.

Below are the most used specifiers in C

The next lesson will teach you C Comments and how to use them in your code.
